Huizcolote I Wastewater Treatment Plant, El Huizcolote, Colima, Mexico

Huizcolote I is a municipal wastewater treatment plant located in El Huizcolote, within the municipality of Manzanillo, Colima, Mexico. The plant serves a small population of 274 residents, reflecting its role in a rural or peri-urban community. It operates under Mexico's national water regulations, which require secondary treatment for discharges into water bodies. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 86.40 m³/day and a current discharge volume of 25.92 m³/day, the facility operates well below its capacity, indicating potential for future growth or seasonal demand. The plant's treatment process aligns with Mexican norms for small-scale facilities under the jurisdiction of CONAGUA. The treated effluent is discharged into local watercourses that drain toward the Pacific Ocean via the coastal watershed of Colima. The region's hydrology supports agricultural and ecological systems, and the plant's secondary treatment helps protect downstream water quality in a state known for its diverse ecosystems and tourism along the Pacific coast.

The plant discharges into local streams that flow toward the Pacific Ocean, part of the Colima coastal watershed. This region supports diverse aquatic life and agricultural activities. Secondary treatment reduces organic pollutants, safeguarding downstream water quality in an area where tourism and fishing are economically important.
